The C++ plugin is totally unusable and I uninstalled it immediately after trying.
But I just made a manual set of syntax highlighting rules for C++, and that's good enough for me.
The git integration and other IntelliJ features make up for the missing C++ navigation and refactoring features for me.
I do everything related to compiling, debugging, and stuff (as well as all git committing and stuff, the IntelliJ git integration is about showing changed lines) from a terminal.
